maybe the usage of block~ with a blocksize-argument less than 64
well, a blocksize of 4 was enough for my ears ...
using hml_shelf with a blocksize of blocksize of 8, the filter becomes pretty unstable ... i've attached an example patch showing this behaviour (you might have to reload it a couple of times) same parameters work fine with blocksizes of 4 and 16 ...
would be great, if you could have a look at it ...
thanks in advance ... tim
